BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to hand operable juicers and in particularhand operable juicers having a drive handle.

2. Background

Hand operated devices for extracting juice most often require the userto place the fruit over a fluted extractor and twist the fruit manually.Manually twisting the fruit is cumbersome and has limited effectivenessfor removing juice. Juice extractors having a handle attached to theextractor are described in U.S. Pat. No. 1,861,426, to Davis et al, andU.S. Pat. No. 1,757,609 to Beardsley et al. The handles shown anddescribed are attached directly to the extractor and provide norotational advantage, whereby turning the handle a given rotationaldegree results in the same amount of rotation of the extractor.Furthermore, these handles extend out over the juice collector andpressing down on the handle creates a tipping force, thereby making thejuicer unstable and difficult to use.

SUMMARY OF THE INVENTION

The invention is directed to a juicer comprising a handle that extendsout from beneath the juice receptacle. With the handle extending frombeneath the juice receptacle, the juicer, of the present invention, ismore stable, whereby pressing down on the handle does not cause thejuicer to tip-over. The handle is coupled with a drive mechanism,whereby when the handle is rotated around the perimeter of the juicer,the pulping crown rotates. In an exemplary embodiment, the drivemechanism comprises gears that may provide a rotational advantage to thehandle rotation, whereby rotation of the handle a given amount aroundthe juicer produces a larger amount of rotation of the pulping crown.For example, the gear ratio may be 2:1, whereby rotation of the handle45 degrees creates 90 degrees of rotation of the pulping crown. Inanother exemplary embodiment, the drive mechanism comprises a crankdrive mechanism. A drive shaft conduit is configured through the base ofthe juice receptacle and extends up to couple with the pulping crown. Adrive shaft extends through the drive shaft conduit and couples thepulping crown with the drive mechanism.

The juicer, as described herein, may be configured for extracting fruitfrom any type of fruit including, but not limited to, citrus fruit,oranges, lemons, grapefruit, watermelons, limes and the like. The juicermay be configured with dimensions to accommodate the various types offruit, or may have different size and/or shaped pulping crowns toaccommodate different fruits. For example, a small pulping crown may beprovided for extraction of juice from lemons and limes and a largerpulping crown may be provided for grapefruit. A pulping crown may haveany suitable shape and size and typically comprises a dome shapedelement comprising a plurality of flutes that extend down from thecrown.

The juice receptacle comprises a perimeter wall and a base. In anexemplary embodiment, the juice receptacle comprises a cylindricallyshaped perimeter wall, however, the perimeter wall may be any suitableshape. The perimeter wall and base are preferably a one-piece unit, suchas a single injection molded part. A juice receptacle may furthercomprise a spout for easy pouring of the extracted juice.

A drive shaft conduit extends up from the juice receptacle base allowingthe drive shaft to couple the drive mechanism with the pulping crown.The extended end of a drive shaft may be configured to couple the filterthereto, and may comprise a notched portion. The drive shaft conduit maybe a separate piece that is configured to couple over an opening in thebase or more preferably is an integral part of the juice receptaclewhereby the drive shaft conduit and juice receptacle are a one-pieceunit.

A drive shaft is configured to couple the pulping crown with the drivemechanism and may be any suitable shape. In an exemplary embodiment, thedrive shaft is generally rod shaped and comprises a crown interlock onone end and a drive coupler on the opposite end. A crown interlock maycomprise one or more notches or wedges that are configured to nest witha drive interlock on the pulping crown. A drive coupler is configured tocouple the drive shaft with the drive mechanism and may comprise anynumber of configurations, depending on the type of drive mechanism. Inthe case of a gear drive mechanism, the drive coupler may comprise gearteeth configured to engage with gear teeth on the drive link end of thehandle. In the case of a crank drive mechanism, the drive coupler may bea crank wedge or an arc shaped piece that is driven by the drive linkend of the handle.

A base extension is configured to provide space for the drive mechanismunder the juice receptacle. The base extension may be an integral partof the juice receptacle, whereby the base extension and the juicereceptacle are a single unit, such as an injection molded single part,or they may be separate parts configured to couple together. A baseextension raises the base of the juice receptacle and may comprise anysuitable geometry including a plurality of feet. In an exemplaryembodiment, the base extension has the same general outer perimetershape as the juice receptacle perimeter wall and in some embodiments isa generally cylindrical shape. A base extension may comprise a handleopening that extends some portion around the perimeter of the baseextension. A handle opening may be a slot that extends about 45 degreesaround the pulping crown rotational axis, for example. A handle openingmay extend any suitable amount around the pulping crown's rotationalaxis including, but not limited about 30 degrees or more, about 45degrees or more, about 60 degrees or more, about 90 degrees or more,about 120 degrees or more, about 150 degrees or more, about 180 degreesor more, and any range between and including the values provided,including from about 30 degrees to about 180 degrees, for example. Handrotation of the handle about the juicer is most ergonomic in the 45degree to 60 degree range. It may be difficult for a user to rotate ahandle more than about 180 degrees.

A filter may be configured to be inserted under the pulping crown andover the juice receptacle. A filter comprises a plurality of filteropenings to allow the juice to pass therethrough. A filter opening maybe configured to allow only juice, or juice and some pulp through. Afilter may be a disk shaped element having a drive shaft opening toallow the drive shaft to pass therethrough and couple with the pulpingcrown. The drive shaft opening may be configured to rest on the driveshaft conduit. For example, the drive shaft conduit may comprise areduced diameter portion on the extended end that is configured to allowthe drive shaft opening of the filter to pass there over. The driveshaft may further comprise a notch or other coupling feature to preventthe filter from spinning during use. The drive shaft opening of thefilter may be circular in shape and comprise a coupling feature such asa notch or protrusion to couple with the drive shaft conduit. In anexemplary embodiment, the filter is configured to rest on the perimeterwall of the juice receptacle. The filter may further be configured tosnap onto the juice receptacle.
